IMPROVEMENT IN MACHINES FOR BUNDLING KINDLIllG-WOOD.

TO ALL WHOM IT MAY CON CERN:

Be it known that I, JQHN RICHARDSON, of New York, inthe county of New York, and State of New York, have invented certain new and useful Improvements in Wood-Bundling Machines;I and I do hereby declare that the following is a full, cleat', and exact description thereof, reference being had -to the accompanying drawings, making part of this speciiicatiom and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use myinvention, I will proceed to describe it.

My invention consists in an improved apparatus forlfeeding wood-to machines for bundling the same, and is more especially intendedjfor use in connection with the machine heretofore invented by Stevens and myself.

In that machine, the wfood was delivered to a sharp-edged tube, which received,- shaped, and held the bundle while being tied; and the apparatus herein described is for the purpose of deli-vering the wood to said tube, or any similar one used for the same purpose.

Figure 1 is a longitudinal vertical section, and

Figure 2 is a top plan view. A

The apparatus consists of a suitable frame, in which are mounted two4 endless belts, as represented by A and B; the under belt A having a portion exposed, on which to place the'wood'; the belt B being mounted on two rolls, D and H, the latter of which is fastened in a frame, having one end pivoted on the journals of the roll D, while the opposite end, with lthe roll H, is left free to be raised or lowered as desired. representing the side bars, and u the cross-bar ofsaid frame. These belts carry the wood forward,` and deliver it through a suitable opening, upon the curved plate 1, shown in iig. 1. A serios of these curved plates, designated 1, 2, and 3, are pivoted one above another, within the circular opening E, which is'intendedV to correspond insizc with and be located directly in the rear of the bundling-tube h'creinbefore alluded to. Upon the journals of these plates are secured spiral springs, as shown at c, iig. 2, which tend to holdthe plates up, as repres'ented'in blue, but which yield as the wood accumulates on the plates, and permit themto be pressed backagainst the side of the opening, as shown in red in lig. 1. The plunger, which presses the' wood into -the sharp-edged tube, as described in the' former application, works through this opening E, it being operated by being shoved forward and drawn back at the proper times, as therein described. When drawn back, the plates 1, 2, and 3 are raised, and the wood is then piled or fed in upon them by the belts A and B, until the opening is full, and the plates shoved back, as indicated in red; and this apparatus is so connected with the machine, thatjust at that instant the plunger F moves forward and drives or shoves the wood out of the opening E into the tube in front of it. In order to prevent the wood from bein-g fed into the' opening at all while theplunger is'being drawn back, there is a section of the plunger, as represented by a, that remains shoved forward, so as to close the opening through which the wood enters AE, and keep it closed until the plunger F gets back out of the way. This section,

a, is made much longer than the body of the plunger, and is arranged so asto slide back and forth; a spiral spring, n, engaging against a. projecting piece, c, attached to the outer end of thesliding section cz, and serving vto keep it hack, so as to keep itsrfront end and the front end of thc plunger F even. After the plunger has been shoved in, and the section a with it, the-projecting piece c slips otffrom the spring t', which rises up, so that its end catches against the projection c, andj thereby holds the section a in place, while the plunger is drawn back, until the latter, having nearly reached its position, strikes the spring z', by an inclined projection, o, which depresses the spring z', thereby releasing the projecting piece c, and permitting the section a to slide back, and thus open the mouth and permit the wood to again enter the opening E, en the plate 1.

In order to prevent the possibility of injury, in consequence of a stick not entering fair, and its front end catching against the side of the case as the plunger shores the wood into the tube, I have a section of the case at that point made movable, and attach it tolguidepins Z Z, end .insert a bent spring, 7L, to hold it in position, but permit it to yield in ease the end of one or more sticks gets caught, against it, the spring causing it to return to its position as soon as the plunger is drawn back. The two belts or aprons that feed the wood forward are connected by a cross-belt, fm, as shown in g. 2, so as to cause them to revolve together, as indicated by arrows in iig. 1, so `as to seize the wood between them and draw it forward; there being notched wheels C and D, to

assist in feeding the wood forward. It is obvious that instead of the belts, endless chains, having spurs or hooks projecting from their surface, may be substituted for feeding tlie wood in.

For the purpose of operating the lever that dogs or undogs the mechanism that operates the plunger, at theproper time, a lever, I), is connected to the journal ofthe plate 3, so that, astlie opening E is lled, and the plate 3 is pressed entirely back, the lever b serves to set the plunger in operation. By these means l am enabled to feed thewood to the machine with facility and certainty.

Having thus described my invention, what I claim, is- ,Y

1. The carrier-belt A, in combination with the" belt B, mounted 4in the hinged or pivoted frame, when arranged to operate substantially as described, for the purpose of feeding the wood to the receiverE, asset forth.

2. The plates \1, 2, 3, so arranged Within the receiver E, to receive the wood, said plates being arranged to yield as the wood is fed in, substantially as described. v y

3.Y The sliding section or slide @,arranged to close the aperture through which the Wood is fed into the receiver E, .and automatically to open the same, as the plunger is drawn back, when constructed substantially as herein shown and described.
